The above described method ,of having the coin itself carry'thecurrent andbecome'a part of thecircuit is objectionable especially Where highyoltage current .is employed, since ,the

solenoid dores Vwillv become so fcorrodedjthat aV positive, .contactA ,isE not.A always Obtained.

To avoidthisVthe construction illustrated in Frigs. Gand? may be employed. In this construction, thesolenoid cores 27 and 28 do not carry current. IThe core sleeve connections'lare eliminated'and thesolenoids all connel lnectedr through conductors 40- ,with contact screwslll carried on, .but insulated from, the

Acircuit diagram which'couldbe employed l 'with the device of Figs. 6 anda?, is shown l to the upper solenoid Ywhere it acts .to

Withdraw the core 27. This allows the coin to fall against the lower core 28 and'force the lowerspring 43 outwardly against `the a e transformer.; VThis energizes the solenoid 46 lower screw 4 1 thereby VVclosing the circuit from the coin chute, to the motor 36 andthe right-hand main 35. The program cam 37 thenV acts to close the circuit to the lowersolemotor circiut between the lower screw 4l'and lower spring 43. K Y

lt will be noted .that in the :latter circuit diagram Vthe audio contact devicehas been eliminated. Any of the control circuits Will operate similarlyjwithout the audiocontact mechanism.

V Both of the aboye'described ormsofv the through v-all'of Y e the controls. In Figs. 8,9, andl2, 1I have illustrated an alternate forni of the: invention designed for employing a low Voltage for-the Y f solenoidsand contacts and highyoltagefor the motor. In this form a VCoin chute `45 car- I ries a pair of solenoids 46 and'47 upon its opposite faces, and upona common core tube48.

The core tube passes through the `coin pas- Y sage, itbeingVcut-away to allowtlie edge of the coin topass through thetube as it passes downwardly inthechute45.

,A magnetic core 49 is arranged toreciproi cate `between the Ysolenoid`s46 and 47, and is provided witha transverse slot'50 which, when in'alignment with the coin chiite 45, will allow `the lcoin to fall to Vthe coin box 39.

On oneextreinity ot the core 49 an insulatingY bushing 51 is carried, provided with a switch cntact, which', .when the core is at the VeX- treme right-hand position, passes between a pair of'switch blades' 53 and closes the circuit therebetween. l

A circuit isthenclosed from the secondary of ythe transformer through ,a f conductor 57, coin chute45, blade 44 screw 59, to ythe opposite secondary.
